No, he can’t, as there’s unfortunately no technical way to do it - at least to my knowledge.
However, if you do know of one, please let us know.
Press ‘Sel’ on the Aux channel you want to use - Go to the Routing Screen - You see ‘Aux Send Settings’ - then ‘Pre-Fade’ - choose ‘All Post’ - then set the individual Channels all to Unity on the Aux channel - and the Aux Volume to the level you want - On L&R whatever channel you have up - it will be reflected in the Aux Channel - You can Use both the Graphic EQ and Parametric EQ on the Aux - in this case rolling off everything about 120 hz - then his Techs don’t have to pay attention to the Aux beyond setting the Aux Master to the level they want - but the OP could set that in advance.
If I understand the entire thread correctly, the OP wants the level of his subwoofers follow the master fader of the Main LR, so that when he turns down his PA, the subwoofers should also turn down.
Therefore, if they were to use an aux mix for their subs (as i generally do too), then its master fader should follow the Main LR master fader.
Or in other words: One master fader for both.
My method does this - the only thing is you have to turn down the subs master - or if you turn down the L/R faders it will dim the faders on the Aux.
And that’s exactly what the OP doesn’t want.
They doesn’t want to have to use an additional subs master, nor does they want to use a DCA fader for both masters - but just one master fader for both.
They have also explained their reasons for this, and we can’t change it.
He would only set it once in practice - what would be the big deal?
He doesn’t just want only set it once, but quite obviously wants to change the overall volume of his PA, including his subwoofers, using only the Master LR fader!
Using a separate aux mix for the subs is (currently) not possible with this requirement.
The only option, as suggested above, would be to use two matrices as a kind of “crossover.”
Then he wouldn’t have a separate sub mix, which he didn’t request, but he would have the ability to control the overall volume with just one knob, which is what he wanted.
Apparently, he’s implemented something similar and seemed satisfied with the result.
He would have the ability to change the sub volume with just one fader - but his techs would have to go to the Aux channel to fade it - if you used to Matricess he would have to go to a different screen just like with the Aux - so it’s one way or another - except with the AUX method he could also control what went to the subs - which he wouldn’t through a Matrix - Right? - am I missing something - it seems like it with your replies?
Sorry - it’s probably my poor English that’s preventing me from expressing myself clearly enough.
He doesn’t want to change the sub volume with just one fader, but rather control the PA and subwoofers TOGETHER with the Main LR Master fader (see red marks in the image).
In both cases, he shouldn’t need to switch to another screen.
But with the two matrices, he has the advantage of never having to worry about it again.
Both are set up once and then function similarly to an external crossover, and he controls both together with just his Main LR Master fader, as desired.
That’s exactly right, and that’s why it’s also my preferred approach.
In my work, I even find it better to have the Subwoofer master permanently available separately.
Yes, but that isn’t an issue for him.
But, as already mentioned several times, this isn’t the workflow of the OP and the volunteers, for whom nothing should change in their current workflow, even though PA and subwoofer are now processed separately in the console.
@SQuser In both cases, he shouldn’t need to switch to another screen.
The Matrix Master Fader are not controlled by the L&R Master Fader - so it’s the same as using the Aux send - but it’s only a Single Fader control of the whole program. - with the Aux the Inputs can be controlled so you aren’t sending something like a vocal to the subs - and you can set the Volume such that the subs aren’t pushing to much volume.
This is IMO the best way to get what the OP wants - generally his techs wouldn’t have to pay attention to it once he set it up correctly -
We seem to be going in circles.
You’re quoting me, but I still have no idea which screens you mean.
I realize again that you haven’t yet grasped the signal flow of the SQ and therefore the differences between the Aux and Matrix.
Please also refer to the relevant documents, such as the block diagram or a signal flow diagram.
The signals from the Main mix are sent to the matrix after the Master fader, so the matrix master faders don’t need to be adjusted.
And what happens if they want to drastically reduce or even mute their Main Mix?
Right - their Submaster Aux would still be audible at full volume.
Please at least try to understand that much.
@SQuser I realize again that you haven’t yet grasped the signal flow of the SQ and therefore the differences between the Aux and Matrix.
Please also refer to the relevant documents, such as the block diagram or a signal flow diagram.
You know I didn’t realize that - in our church I rarely use the Matrices - great info.
Even if you only use something rarely, you should know how it works!
And, I’m sorry, but I don’t understand why someone who obviously doesn’t know how a function works and still doesn’t even bother to follow detailed explanations about it, spends days discussing and trying to educate others, thereby confusing them.
But no hard feelings.
The routing config has been gone over many times now…..use a DCA.
As for the sub processing…….use a crossover the for the low pass and even the high pass for the sub low frequency protection. Grabbing a bunch of faders on an EQ does not make a crossover cut off same goes for a high or low shelf on the parametric EQ.
I know how it works - It’s easier for us to control the subs to use the Aux sends.
